McHenry County, Illinois, is a picture-perfect farming community in the Heartland of Midwestern America. For nearly two centuries, a portion of the nation's food supply has come from this fertile land near the Fox River, and it has played a key role in the history of Chicago and the United States. Through the medium of historic photographs, this book captures the evolution of the people of McHenry County, from the mid-1800s to the second half of the twentieth century. These pages bring to life the people, events, communities, and industries that helped shape and transform McHenry County. With more than 200 vintage images, culled from three collections-the McHenry County Historical Society, the Crystal Lake Historical Society, the James Keefe Collection, and the personal collection of Don Peasley-McHenry County, Illinois, portrays life against a backdrop of international wars, national social struggles, and technological advances in an expanding world.
